It is my opinion that chivalry, originally dictating a code of conduct for helping women, in a point of time within which women were not equal to men.

Now that women are equal to men, Chivalry no longer serves it's purpose, and those complaining are simply whining about the lack of attention. That very same attention, which could be directed towards women under the guise of chivalry in situations where a more direct approach cannot be used, is very effective in scoring points with the ladies

No doubt they're both lies. I myself keep at the average American height for my age: 5'10"
I can tell those who are American by the ones who realize the "average American height" is an outright falsehood. And I can tell the ones who actually care what I say by who actually comments on this.
